Abstract

(57) [Summary] [Purpose] The residual grains in the sorting barrel are discharged using a spiral brush that removes the clogging of the pot hole, and serves the dual role of removing the clogging and discharging the residual grains. This makes the discharge quick and easy. [Structure] A helical brush (3) is forcibly rotatably provided on the inner peripheral surface of the sorting cylinder (2) from the supply side to the discharge side, and the helical brush (3) is rotated around the rotation axis of the sorting cylinder (2). The helical brush (3) is horizontally mounted so as to be freely switchable between an initial position (4) on the upward rotation side and a position (5) near the final stage on the downward rotation side.
When it is located in the pot hole (1), it presses into the pot hole (1) and returns to the initial position (4).
The structure is such that when the grain is displaced to the discharge side, grains that are unevenly distributed and flowing on the inner circumferential surface of the sorting cylinder (2) are transferred to the discharge side.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a residual grain discharge device in a rotary sorting huller. The rotary sorting and hulling machine consists of a shedding section for shedding paddy and a system for sorting the scraped material from this shedding section. The brown rice after passing through the wind sorting part is It consists of a rotary sorting unit that sorts the mixed rice of rice and paddy. It can be used to quickly expel residual grains.

0002

[Conventional technology]

Conventionally, in a rotary sorting huller configured as described above, the selection in the rotary sorting section has been carried out. It is actually used as a device in which a helical brush is horizontally mounted from the supply side to the discharge side in a separate cylinder. There is something like the one disclosed in Publication No. 179379/1980, but there is a The helical brush of the loaded item is pressed against the downward rotating side of the sorting cylinder and attached to the pot hole. One of its functions is to remove the clogs that accumulate on the surface.

[Problem that the idea aims to solve]

The sorting cylinder has many potholes formed on its inner circumferential surface and is hung horizontally so that it can rotate freely. In the rotary sorting huller that sorts the mixed rice from the wind sorting section, the process ends. At times, grains remain in the sorting barrel, and to remove them, the feed side is raised and the machine is tilted. However, this conventional method is time-consuming and labor-intensive. The present invention discharges this residual grain using a spiral brush that removes the clogging of the pot hole. It is possible to carry out two tasks: removal of blockages and discharge of residual grains. This allows the discharge to be carried out in a short period of time and without tilting the aircraft. This has been improved and devised for the purpose of making it easier.

[Means to solve the problem]

Therefore, the present invention provides a rotary sorting huller that can achieve the above-mentioned objectives. In order to A helical brush is forcibly rotatably provided from the discharge side to the discharge side, and the helical brush The initial position of the upward rotation side and the downward rotation side are centered around the rotation axis of the sorting cylinder. The helical brush is placed horizontally so that it can be switched freely between the position near the final stage, and the helical brush When it is in the position, it presses against the pot hole, and when it is moved to the initial position, it is biased against the inner peripheral surface of the sorting cylinder. The structure is such that the grains that are present and flowing are transferred to the discharge side.

[0005]

[Effect]

With this configuration, the helical brush can be selected during hulling work. Position it near the end of the downward rotation side of the separate cylinder and form it on the inner peripheral surface of the sorting cylinder. If the pot is pressed against the pot hole, it will prevent the bran from adhering to the pot hole and trying to deform the pot hole. Clogging such as fine dust is removed by the forced rotating helical brush and the jar is constantly cleaned. Clean the hole to maintain its original shape and improve the lifting effect of brown rice, and also to clean it at the end of the work. If the helical brush is moved to the initial position on the upward rotation side, the forced rotation will occur. Due to the feeding action of the helix, the grains remaining unevenly distributed in the barrel and flowing are removed to the discharge side. The material is then transferred towards the end of the barrel, and is discharged from the discharge side.
